I only make coasters (at 24x) if I use dime-store CDRs. Also, the CD-Writing howto has all the info you need for writing CDs, although it sounds like you've done your homework. // John Bleichert // syborg(a)earthlink.net

My burner reads at 52x, writes up to 8x. It is a LG. I usually write at 4x or 3x. I was trying to create an audio CD trying to recover a very scratched CD. Grip very slowly has recovered all tracks after some extra cleanning. I was trying to write with: cdrecord -v speed=2 dev=0,0,0 -pad *.wav And it was returning with error. Then I added -dao: cdrecord -v speed=2 -dao dev=0,0,0 -pad *.wav Now, it is working... It is burning track 7 so far.
